Bug#1080481: Fix compilation of Webcamoid against ffmpeg 7.0

[Nicola Ferralis]

Package: webcamoid
Version: 9.1.1-1


The source code of Webcamoid is incompatible with the current version of FFmpeg 
7, leading to a crash when trying to compile against it.
The attached patch fixes the issues, allowing successful compilation.

I am using Ubuntu 24.04 and Debian Unstable.
